Espire Infolabs specializes in developing large-scale enterprise applications. As part of the backend team, I have worked on multiple modules of Warehouse Management Systems and sustainability projects, focusing on performance optimization, microservices migration, and API design.

Key Responsibilities and Achievements:

• Designed and developed RESTful APIs for subscription management, feature deployment, and service request handling using Spring Boot and PostgreSQL .
• Migrated legacy SOAP services to microservices , improving system scalability and maintainability.
• Containerized services with Docker and deployed them on Kubernetes , ensuring stable and consistent environments.
• Optimized SQL queries and implemented indexing to improve database efficiency and reduce response time.
• Integrated Spring Security and JWT-based authentication for secure API communication.
• Collaborated with cross-functional teams (frontend, QA, DevOps) in an Agile environment to deliver reliable and high-performance solutions.
• Built CI/CD pipelines using Jenkins for automated testing and deployment, minimizing manual errors and release time.

Major Projects

LogiLore Warehouse Management System (2022 – Present)

• Developed backend modules for a customizable warehouse management platform that allows clients to configure business-specific features.
• Implemented a subscription-based feature management system to manage deployments across multiple environments and regions.
• Improved performance of key APIs by optimizing query execution and database schema design.
• Coordinated with frontend and DevOps teams to ensure seamless integration and smooth deployment cycles.
• Participated in sprint planning and bug resolution to ensure timely, high-quality releases.

COE Warehouse Management Migration Project (2022)

• Led the migration from legacy SOAP-based services to modern RESTful microservices using Spring Boot .
• Developed APIs to ensure consistent communication between microservices.
• Deployed applications using Docker and Kubernetes , improving scalability and reducing deployment downtime.
• Supported CI/CD pipeline integration to streamline deployment and testing processes.
• Enhanced maintainability by implementing modular microservice design and detailed API documentation.

Carbon Emission Calculator (2023 – 2025)

• Developed a carbon footprint calculator to estimate CO₂ emissions based on travel distance between a source and destination.
• Used Java, Spring Boot, and PostgreSQL to design and implement emission calculation APIs.
• Integrated geolocation APIs to determine accurate travel distances and applied emission factors for various transport modes.
• Created RESTful APIs for calculating, storing, and retrieving emission data, enabling third-party integration.
• Optimized database queries to handle high request volumes efficiently, reducing response time .
• Collaborated with the product and frontend teams to ensure seamless data exchange and reliable user experience.
